I have a hard time believing those terms of conditions meets the inquiry notice requirements and would stand up in court against anonymous internet users.
I view a website and someone says I owe them my first born, does not make it so.
It wouldnt for many sites but it just wasn't a problem before because the value exchange held. Privacy laws and adblocking are causing these to become more visible with explicit Accept buttons however there's still the obstacle of proving identity online.
Anyways, this is something that paywalls solve entirely so it's a great model, but nobody wants to pay.
